This is a RARE, vintage, 1940 LONGINES chronograph housing the legendary 13ZN movement, which was an in-house movement produced by LONGINES and is of the finest quality. The original 35mm.18k. solid gold LONGINES snap-back case has very subtle and usual ding marks barely visible on the side. This watch is thick, at 13.5mm. The prized all ORIGINAL dial with original blued steel hands is evenly aged with blue (rare) PULSATIONS scale. I really love the spectacular patina this dial has taken on over the years! Notice the serial number on the movement also matching the case.
